Hat tip to the Lowy Institute for the first of three video clips; the thread's title is mine:
Dr Sims, regarded as one of world's leading experts on intelligence, having previously served as Deputy Assistant Secretary of State for Intelligence Coordination for the US State Department, led a fascinating discussion about the changing nature of intelligence and the challenges facing intelligence services.

We recorded a long video discussion with Jennifer which we have broken up into three parts. In this first video (5 mins), Dr Sims looks at the information revolution – how the rise of the internet has fundamentally altered intelligence-gathering techniques, bringing challenges and opportunities in a globalised security environment.
